@ELM ,
I suffered a neck injury 25 years ago in a high school wrestling accident. Trap, lats, and general neck pain and stiffness has plagued me for those 25 years until I started doing original strength reset from original strengths tactical athlete and pressing reset books. Been doing it for about 1.5 months, I have never felt better. I feel like this has greatly improved my s&s experience.
For the record, the time I've been doing the resets has been more effective than doctors, massage therapy, foam rolling, stretching, yoga, etc... over the previous 25 years.
Just my experience, not saying it's a fix all or even the answer for you.
